Benjamin, Out of curiosity, which UPS do you have ? From the link below which NUT driver does it use ?
http://www.networkupstools.org/stable-hcl.html I personally would not trust a USB->Serial dongle for UPS communication, but it may possibly work. We do have CONFIG_USB_SERIAL_FTDI_SIO=m in our kernel. Do you have a spare serial port other than the console port on your AstLinux hardware ? Lonnie On Dec 28, 2013, at 7:15 PM, Benjamin L.
